She was educated at Notting Hill & Ealing High School in London and left school with nine GCSEs and A-levels in physics, mathematics and chemistry. Huq studied sciences for her A-Levels, but chose to study economics at Robinson College, Cambridge and graduated from Cambridge University with a 2:1 degree.
In 1989, at the age of 14, Huq was a guest on Blue Peter with the National Youth Music Theatre, when she sang a solo.

For the programme's 2004 "Welcome Home" appeal, she made an emotional visit to Angola hoping to reunite children with their families (from which both had been separated due to war). In 2008, during her last programme, she broke a Guinness World Record by managing to pin 17 Blue Peter Badges onto fellow presenter Andy Akinwolere's shirt in a minute.
